BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed wiring board loading/receiving device capable of continuously loading printed wiring boards into a surface treatment device and continuously receiving printed wiring boards discharged from the surface treatment device. . More specifically, the present invention allows printed wiring boards to be continuously fed into a surface treatment device unattended in a package suitable for transportation and storage, and also enables printed wiring boards discharged from the surface treatment device to be unattended. The present invention relates to a printed wiring board loading/receiving device that can continuously receive printed wiring boards in the loaded state.

Stacking printed wiring boards has the advantage that a large quantity can be transported at one time, and that less floor space is required during storage. However, if the substrates are directly laminated, scratches and the like will occur on the surfaces, causing problems. Additionally, there is a risk of damage due to cargo collapse during transportation. Therefore, it is desired to develop a printed wiring board loading/receiving device that does not have such a fear.

Sensors 63 and 64 are provided on the entrance and exit sides of the filing device, respectively, and during filing (when pushing each board 25 upward in sequence with a predetermined interval apart), the sensor 63 moves the board 25 upward.
After confirming the passage of the board 25, the file bar 61 moves up one pitch to prepare for the next board 25 to be carried in. In addition, at the time of ejection, the file bar 6
1 moves down by one pitch and sends out the next substrate 25 in sequence. That is, the file bar 61 is set to 1 during both file and ejection.
It is designed to rise or fall in pitch increments.

They are connected by an air cylinder 70 for driving a centering rod.

With this configuration, when the substrate 25 is carried from the filing device section 14 to the receiving conveyor section 35 of the receiving device 16, the centering rods 66 on both sides, which were initially fully open as shown in FIG. By driving the cylinder 70, the substrates 25 are moved toward each other, and the substrates 25 are centered in the Y-axis direction. Note that a servo motor may be used instead of the air cylinder 70.

By driving the XY arm 28, the substrate 25 is conveyed to the input conveyor section 21, and the interlayer protective material 26 is conveyed to the interlayer protective material take-out section 22. The printed wiring board 25 is automatically loaded into the surface treatment device 12 from the loading conveyor section 21 .

All the substrates 25 from the tray 24b being loaded
When the interlayer protective material 26 is removed, the combination sensor 59 detects that the tray 24b is empty,
The empty tray 24c is delivered to the empty tray delivery conveyor section 23 by driving the tray delivery conveyor 44. This empty tray 24c is conveyed by the shuttle mechanism 29 along the railway 18 to the empty tray carrying-in conveyor section 38 of the receiving device 16, and by carrying this empty tray 24c to the loading conveyor section 36, the same substrate 24c is placed on the same tray. can be accommodated. With this configuration, information can be written directly on the tray by pasting documents on the tray 24, writing a bar code on the tray 24, or attaching an IC card, thereby facilitating automated production. Management becomes possible.

The substrate 25 whose surface has been processed by the surface processing device 12 is transported to the filing device section 14 . As described above, in the filing device section 14, the first filing device section 14a and the second filing device section 14b are arranged in parallel.
While receiving the substrate 25 in step 4a), the other filing device section 14b can deliver the substrate 25 to the receiving device 16 on the downstream side. In the filing device section 14, the board 2
5 is reversed and conveyed to the receiving device 16.

The substrate 25 carried into the receiving conveyor section 35 of the receiving device 16 is centered in the Y-axis direction by the substrate centering device shown in FIGS. 16 to 18. An empty tray 2 is placed on the loading conveyor section 36 of the receiving device 16.
4c is carried in, and by driving the X-Y arm 40, the substrates 25 on the receiving conveyor section 35 and the interlayer protective material 26 on the interlayer protective material stock section 39 are alternately attracted and stacked in the tray 24. and accommodated. The tray 24 containing the substrate 25 and the interlayer protection material 26 is conveyed to the stock conveyor section 37 and once stocked, and then transferred to an automatic guided vehicle or the like as necessary.

Input device 10 and receiving device 16 of this embodiment
Since they have roughly the same configuration, the input device 10 and the receiving device 16 can be used interchangeably by changing the program. This makes it easy to change the left and right hand.

By storing the number of substrates inputted by the loading device 10 in the electronic control device and receiving them into the tray by the receiving device 16 via the filing device 14, it is possible to reliably load the same number of substrates into the tray. The same effect can be obtained even if instead of storing the number of substrates inserted, the time at which they were inserted is stored and the receiving device 16 receives them.

(1) Since the input device and the receiving device are highly compatible, it is easy to use them for other purposes. (2) Continuous loading and receiving is possible because trays are used that are highly transportable and easy to store. (3) Lot management is possible, making production management easier.
